<p>The package <b class="package">pop3d::dbox</b> provides simple/basic mailbox
management facilities. Each mailbox object manages a single base
directory whose subdirectories represent the managed mailboxes. Mails
in a mailbox are represented by files in a mailbox directory, where
each of these files contains a single mail, both headers and body, in
RFC 822 (<a href="http://www.rfc-editor.org/rfc/rfc822.txt">http://www.rfc-editor.org/rfc/rfc822.txt</a>) conformant
format.</p>
<p>Any mailbox object following the interface described below can be used
in conjunction with the pop3 server core provided by the package
<b class="package"><a href="pop3d.html">pop3d</a></b>. It is especially possible to directly use the objects
created by this package in the storage callback of pop3 servers
following the same interface as servers created by the package
<b class="package"><a href="pop3d.html">pop3d</a></b>.</p>
<dl class="doctools_definitions">
<dt><a name="1"><b class="cmd">::pop3d::dbox::new</b> <span class="opt">?<i class="arg">dbName</i>?</span></a></dt>
<dd><p>This command creates a new database object with an associated global
Tcl command whose name is <i class="arg">dbName</i>.</p></dd>
</dl>
<p>The command <b class="cmd">dbName</b> may be used to invoke various operations on
the database.  It has the following general form:</p>
<dl class="doctools_definitions">
<dt><a name="2"><b class="cmd">dbName</b> <i class="arg">option</i> <span class="opt">?<i class="arg">arg arg ...</i>?</span></a></dt>
<dd><p><i class="arg">Option</i> and the <i class="arg">arg</i>s determine the exact behavior of the
command.</p></dd>
</dl>
<p>The following commands are possible for database objects:</p>
<dl class="doctools_definitions">
<dt><a name="3"><i class="arg">dbName</i> <b class="method">destroy</b></a></dt>
<dd><p>Destroys the mailbox database and all transient data. The directory
associated with the object is not destroyed.</p></dd>
<dt><a name="4"><i class="arg">dbName</i> <b class="method">base</b> <i class="arg">base</i></a></dt>
<dd><p>Defines the base directory containing the mailboxes to manage. If this
method is not called none of the following methods will work.</p></dd>
<dt><a name="5"><i class="arg">dbName</i> <b class="method">add</b> <i class="arg">mbox</i></a></dt>
<dd><p>Adds a mailbox of name <i class="arg">mbox</i> to the database. The name must be a
valid path component.</p></dd>
<dt><a name="6"><i class="arg">dbName</i> <b class="method">remove</b> <i class="arg">mbox</i></a></dt>
<dd><p>Removes the mailbox specified through <i class="arg">mbox</i>, and the mails
contained therein, from the database. This method will fail if the
specified mailbox is locked.</p></dd>
<dt><a name="7"><i class="arg">dbName</i> <b class="method">move</b> <i class="arg">old new</i></a></dt>
<dd><p>Changes the name of the mailbox <i class="arg">old</i> to <i class="arg">new</i>.</p></dd>
<dt><a name="8"><i class="arg">dbName</i> <b class="method">list</b></a></dt>
<dd><p>Returns a list containing the names of all mailboxes in the directory
associated with the database.</p></dd>
<dt><a name="9"><i class="arg">dbName</i> <b class="method">exists</b> <i class="arg">mbox</i></a></dt>
<dd><p>Returns true if the mailbox with name <i class="arg">mbox</i> exists in the
database, or false if not.</p></dd>
<dt><a name="10"><i class="arg">dbName</i> <b class="method">locked</b> <i class="arg">mbox</i></a></dt>
<dd><p>Checks if the mailbox specified through <i class="arg">mbox</i> is currently locked.</p></dd>
<dt><a name="11"><i class="arg">dbName</i> <b class="method">lock</b> <i class="arg">mbox</i></a></dt>
<dd><p>This method locks the specified mailbox for use by a single connection
to the server. This is necessary to prevent havoc if several
connections to the same mailbox are open. The complementary method is
<b class="method">unlock</b>. The command will return true if the lock could be set
successfully or false if not.</p></dd>
<dt><a name="12"><i class="arg">dbName</i> <b class="method">unlock</b> <i class="arg">mbox</i></a></dt>
<dd><p>This is the complementary method to <b class="method">lock</b>, it revokes the lock
on the specified mailbox.</p></dd>
<dt><a name="13"><i class="arg">dbName</i> <b class="method">stat</b> <i class="arg">mbox</i></a></dt>
<dd><p>Determines the number of messages in the specified mailbox and returns
this number. This method fails if the mailbox <i class="arg">mbox</i> is not
locked.</p></dd>
<dt><a name="14"><i class="arg">dbName</i> <b class="method">size</b> <i class="arg">mbox</i> <span class="opt">?<i class="arg">msgId</i>?</span></a></dt>
<dd><p>Determines the size of the message specified through its id in
<i class="arg">msgId</i>, in bytes, and returns this number. The command will
return the size of the whole maildrop if no message id was specified.
If specified the <i class="arg">msgId</i> has to be in the range &quot;1 ... [<i class="arg">dbName</i> <b class="method">stat</b>]&quot;
or this call will fail. If <b class="method">stat</b> was not called before this
call, <b class="method">size</b> will assume that there are zero messages in the
mailbox.</p></dd>
<dt><a name="15"><i class="arg">dbName</i> <b class="method">dele</b> <i class="arg">mbox msgList</i></a></dt>
<dd><p>Deletes the messages whose numeric ids are contained in the
<i class="arg">msgList</i> from the mailbox specified via <i class="arg">mbox</i>.
The <i class="arg">msgList</i> must not be empty or this call will fail.
The numeric ids in <i class="arg">msgList</i> have to be in the range &quot;1 ...
[<i class="arg">dbName</i> <b class="method">stat</b>]&quot; or this
call will fail. If <b class="method">stat</b> was not called
before this call, <b class="method">dele</b> will assume
that there are zero messages in the mailbox.</p></dd>
<dt><a name="16"><i class="arg">storageCmd</i> <b class="method">get</b> <i class="arg">mbox</i> <i class="arg">msgId</i></a></dt>
<dd><p>Returns a handle for the specified message. This handle is a mime
token following the interface described in the documentation of
package <b class="package"><a href="../mime/mime.html">mime</a></b>. The token is <em>read-only</em>. In other
words, the caller is allowed to do anything with the token except to
modify it.
The <i class="arg">msgId</i> has to be in the range &quot;1 ...
[<i class="arg">dbName</i> <b class="method">stat</b>]&quot; or this
call will fail. If <b class="method">stat</b> was not called
before this call, <b class="method">get</b> will assume
that there are zero messages in the mailbox.</p></dd>
